Operational data rationalization

ABSTRACT

An approach is provided for rationalizing operational data. Persisted knowledge of previous data transactions is determined to not include a previous data profile matching a current data profile. Stochastic data sampling generates a sample of a current dataset. Data size and shape corrections are determined and updated by iterations of a statistical inference technique. Data in the sample is corrected by using the data size and shape corrections to provide a confidence level exceeding a threshold. Persisted knowledge configurations are updated with parameters of the statistical inference technique, the data size and shape corrections, and filtering rule(s). A recommended modification of a query of a current data transaction is determined to provide data in the current dataset with the level of confidence exceeding the threshold. The recommended modification is applied to the query.

TECHNICAL FIELD

The present invention relates to managing operational data, and more particularly to automatically rationalizing operational data in enterprise application systems.

BACKGROUND

Over many years of running and elapsed operations of a business, the business accumulates a large amount of data that needs to be organized between archives and active usage for data analysis for business purposes. Because of the enormous size of the accumulated data and because of a significant amount of redundancies in the data, extracting references for analysis is an extremely difficult task that is slow and inefficient. The business may have the difficult decision of whether to discard data archives or retain them for historical business references. Further, business dimensions influenced by effective information technology (IT) and storage systems demand more business situation centric data for use in regular business operations and analytics. Still further, known redundant and static procedures of an enterprise that analyzed data in a previous cycle of transactions or a few years ago may not produce appropriate results for a current transaction in the enterprise because business dynamics have changed.

DETAILED DESCRIPTION

Overview

Embodiments of the present invention transform raw context-free operational data into context-sensitive data. The context is derived from the way transactions were treated earlier and persisted as knowledge for similar situations in future transactions. The context is dynamic to business sensitivity of data as directed in the data profile in day-to-day transactional endeavors. The context is also a knowledge which is corrective of adjustments to a business situation, environment, circumstance, or perspective. A dynamically changing business situation is the basis for determining a context of the operational data by iteratively using attributes of the business situation in the recent past. Embodiments of the present invention rationalize stored transactional data of an enterprise for effective use based on a business situation, by using inherent intelligence in data persisted from previous rationalizations of transactional data. The persisted data provides more knowledge about business dynamics than does static processes.

In one embodiment, a cyclic method includes steps of Load, Infer, Filter, and Enable (also referred to herein as the LIFE method or simply as the acronym of LIFE), which are implemented by an augmentation gateway (i.e., a proxy server) and knowledge persistence tool. In the Load step, an incoming request from a requesting application includes switches indicating a data access method and a type of data and results in data extracted from a dataset. In the Infer step, the data set is validated for fitment to relationships suggested by the requesting application, and the request is provided with switches for using predetermined statistical inference algorithms in standard statistical applications. In the Filter step, a sampling technique is used to transform the dataset to a dataset nearest to the population representation. In the Enable step, the data is permitted to repeat a cycle of analysis or final policies on the dataset are returned to the requesting application.

System for Rationalizing Operational Data

FIG. 1 is a block diagram of a system 100 for rationalizing operational data, in accordance with embodiments of the present invention. System 100 includes a computer 102, which executes a software-based operational data rationalization system 104. Computer 102 includes an augmentation gateway 106 and a data repository 108, which includes persisted knowledge 110. Augmentation gateway 106 can be a proxy server in the path of two or more transacting business applications or components to business rationalize the transactions between the business applications or components. Operational data rationalization system 104 receives an initial dataset 112 via augmentation gateway 104 and outputs a final dataset 114 via augmentation gateway 104.

Operational data rationalization system 104 provides an iterative method that includes load, infer, filter, and enable processes. The sequence of load, infer, filter, and enable processes is also referred to herein as LIFE. Intelligent configurations for datasets are stored in persisted knowledge 110 from a previous performance of LIFE. Augmentation gateway 106 receives a data transaction utilizing a dataset, checks prerequisites to validate the data size, quantities, security, etc. of the dataset, changes the data size and/or data shape in the dataset, and updates persistent knowledge 110 with the dataset changes, which is used in processing a subsequent data transaction. If a change in data presentation of the dataset is not needed, the process request is forwarded from the load process directly to the enable process.

When a request is made for a specific data analysis, operational data rationalization system 104 checks the earlier configurations stored in persisted knowledge 110. If the conditions in persisted knowledge 110 are the same as the request, then the process bypasses the infer and filter processes and continues with the enable process. Otherwise, the request goes through the infer and/or the filter process for sequential application of statistical inferences for viability and filtering the size of data for effective use of the data.

In one embodiment, augmentation gateway 106 sends continuous stochastic referencing from operational data models of an enterprise to operational data rationalization system 104, which provides a framework for both operational data transactions, as well as reassessment of an operational data store based on scheduled studies. By iterating functions provided by a combination of the load, infer, filter, and enable processes, operational data rationalization system 104 updates persisted knowledge 110 with acquired knowledge about an operational data model and stochastic switches.

In one embodiment, the load process receives initial dataset 112 from augmentation gateway 106 to identify presented data in initial dataset 112 for model qualifications. The load process uses stochastic models and data sampling to determine a recommendation for a type of predetermined stochastic switch or rebuilt stochastic model on an earlier known stochastic switch to a new stochastic switch for a data sample to be selected from initial dataset 112.

In one embodiment, the infer process groups and/or samples data in initial dataset 112 to determine a sample for assessment in the data rationalization process. The infer process uses stochastic models and the sample from initial dataset 112 to run statistical inferences.

In one embodiment, the filter process designs and formulates filter rules and makes recommendations for filtering data from initial dataset 112. The filter process uses applied stochastic switches to determine recommendations for modifying initial dataset 112.

The enable process imposes rules resulting from the recommendations for filtering to realize rationalization on the initial dataset 112, which results in a final dataset 114 (i.e., approved transactional dataset). The enable process returns the finalized logic resulting from the load, infer, and filter processes, the load and filter processes (bypassing the infer process), or the load process (bypassing the infer and filter processes) and stores the results in the persisted knowledge 110.

Operational data rationalization system 104 determines enterprise data rationalization objectives based on the operational data models (i.e., selective integrator for correlative assessment between initial dataset 112 and final dataset 114).

Operational data rationalization system 104 uses persisted knowledge 110 to determine applied stochastic switches on a data sample for assessment and stochastic model-based switches and data sampling.

Although not shown in FIG. 1, integrators for enterprise transactional data and data model change management may receive indications that the data model being used by operational data rationalization system 104 is deficient in terms of curve fitting (e.g., by an appropriate statistical test) and extracting the variance among the sample analyzed and assessed from initial dataset 112.

The functionality of the components of FIG. 1 is described in more detail in the discussions presented below relative to FIG. 2, FIGS. 3A-3B, FIG. 4, FIG. 5 and FIG. 8.

Process for Rationalizing Operational Data

FIG. 2 is a flowchart of a process of rationalizing operational data, where the process is implemented in the system of FIG. 1, in accordance with embodiments of the present invention. The process of FIG. 2 starts at step 200. In step 201, augmentation gateway 106 (see FIG. 1) determines whether a current data transaction for an enterprise is a new data transaction of a type that has not been previously recorded in a registry of transactions that have been previously processed by operational data rationalization system 104 (see FIG. 1). If augmentation gateway 106 (see FIG. 1) determines in step 201 that the current data transaction is not a new data transaction (i.e., by determining that a source, destination, and service or data connection being used by the current data transaction matches a record in the registry), then the No branch of step 201 is taken and step 202 is performed.

Prior to step 202, operational data rationalization system 104 (see FIG. 1) receives initial dataset 112 (see FIG. 1) via augmentation gateway 106 (see FIG. 1). In step 202, operational data rationalization system 104 (see FIG. 1) determines the data profile of initial dataset 112 (see FIG. 1), which is being utilized in a current data transaction for an enterprise.

In step 204, operational data rationalization system 104 (see FIG. 1) determines whether persisted knowledge 110 (see FIG. 1) includes a previous data profile that matches the data profile determined in step 202, where the previous data profile is a data profile of a previous dataset that was utilized in a data transaction of the business that was processed by LIFE prior to the current data transaction. If operational data rationalization system 104 (see FIG. 1) determines in step 204 that persisted knowledge 110 (see FIG. 1) does not include the previous data profile that matches the data profile determined in step 202, then the No branch of step 204 is taken and step 206 is performed.

In step 206, operational data rationalization system 104 (see FIG. 1) performs the sequence of the load process, the infer process, the filter process and the enable process, which is described below in the discussion of FIG. 3.

Returning to step 204, if operational data rationalization system 104 (see FIG. 1) determines that persisted knowledge 110 (see FIG. 1) includes the previous data profile of the previous dataset that matches the data profile determined in step 202, then the Yes branch of step 204 is taken, and step 208 is performed.

In step 208, operational data rationalization system 104 (see FIG. 1) determines whether persisted knowledge 110 (see FIG. 1) includes an indication that a data size correction and/or a data shape correction was applied to the previous dataset. If operational data rationalization system 104 (see FIG. 1) determines in step 208 that persisted knowledge 110 (see FIG. 1) includes an indication that a data size correction and/or a data shape correction was applied to the previous dataset, then the Yes branch of step 208 is taken and step 210 is performed.

In step 210, operational data rationalization system 104 (see FIG. 1) performs the sequence of the load process, the filter process, and the enable process (i.e., bypassing the infer process in LIFE), which is described below in the discussion of FIG. 4.

Returning to step 208, if operational data rationalization system 104 (see FIG. 1) determines that persisted knowledge 110 (see FIG. 1) does not include an indication that a data size or data shape correction was applied to the previous dataset, then the No branch of step 208 is taken and step 212 is performed.

In step 212, operational data rationalization system 104 (see FIG. 1) performs the sequence of the load process immediately followed by the enable process (i.e., bypassing the infer and filter processes in LIFE), which is described below in the discussion of FIG. 5.

Step 214 follows each of steps 206, 210 and 212. In step 214, the process of FIG. 2 ends.

Returning to step 201, if augmentation gateway 106 (see FIG. 1) determines in step 201 that the current data transaction is a new data transaction (i.e., by determining that a source, destination, and service or data connection being used by the current data transaction does not match any record in the registry), then the Yes branch of step 201 is taken and step 206 is performed, as described above.

Load-Infer-Filter-Enable

FIGS. 3A-3B depict a flowchart of a load-infer-filter-enable process included in the process of FIG. 2, in accordance with embodiments of the present invention. The process of FIGS. 3A-3B begins at step 300 in FIG. 3A, which follows the No branch of step 204 (see FIG. 2). In step 302, based on the current data transaction being a new data transaction (i.e., taking the Yes branch of step 201 in FIG. 2) or based on persisted knowledge 110 (see FIG. 1) not including a previous data profile that matches the data profile determined in step 202 (see FIG. 2), operational data rationalization system 104 (see FIG. 1) generates a sample of initial dataset 112 (see FIG. 1) by employing a stochastic sampling technique.

In step 304, based on the current data transaction being a new data transaction or based on persisted knowledge 110 (see FIG. 1) not including a previous data profile that matches the data profile determined in step 202 (see FIG. 2), operational data rationalization system 104 (see FIG. 1) determines a data size correction and/or a data shape correction by employing one or more inference techniques (e.g., a combination of mathematical, quantitative, statistical, rated multipliers, quadratic, linear and nonlinear, fuzzy logic, etc.).

In step 306, operational data rationalization system 104 (see FIG. 1) determines one or more filtering rules for correcting initial dataset 112 (see FIG. 1) based on the data size and/or data shape corrections determined in step 304.

In step 308, operational data rationalization system 104 (see FIG. 1) adds or updates configurations in persisted knowledge 110 (see FIG. 1) with parameters of the inference employed in step 304, the data size and/or data shape corrections determined in step 304, and the filtering rule(s) determined in step 306.

In step 310, based on the added or updated configurations in persisted knowledge 110 (see FIG. 1), operational data rationalization system 104 (see FIG. 1) generates recommendations of modifications to one or more queries and data collection scenarios of the current data transaction.

In step 312, operational data rationalization system 104 (see FIG. 1) determines a level of confidence that an application of the recommendations generated in step 310 matches requirements of the business. Step 312 is followed by step 314 in FIG. 3B.

In step 314, operational data rationalization system 104 (see FIG. 1) determines whether the level of confidence determined in step 312 (see FIG. 3A) exceeds a threshold level of confidence, which was received by operational data rationalization system 104 (see FIG. 1) prior to the start of the process of FIG. 2.

If operational data rationalization system 104 (see FIG. 1) determines in step 314 that the level of confidence determined in step 312 (see FIG. 3A) does not exceed the threshold level, then the No branch of step 314 is taken, and step 316 is performed.

In step 316, operational data rationalization system 104 (see FIG. 1) repeats the steps in FIGS. 3A-3B that occurred prior to step 316, until the level of confidence is improved enough to exceed the threshold level.

Returning to step 314, if operational data rationalization system 104 (see FIG. 1) determines that the level of confidence determined in step 312 (see FIG. 3A) exceeds the threshold level, then the Yes branch of step 314 is taken, and step 318 is performed.

In step 318, based on the updated configurations in persisted knowledge 110 (see FIG. 1) and the level of confidence exceeding the threshold, operational data rationalization system 104 (see FIG. 1) modifies one or more actual queries and/or one or more data collection scenarios of the current data transaction. The process of FIG. 3 ends at step 320.

After processing the current data transaction as a new data transaction, augmentation gateway 106 (see FIG. 1) adds the attributes of the current data transaction (i.e., source, destination, and service or data connection utilized by the transaction) to the registry, so that processing a subsequent data transaction that is similar to the formerly new data transaction includes augmentation gateway 106 (see FIG. 1) identifying the subsequent data transaction as a known transaction (i.e., augmentation gateway 106 (see FIG. 1) finds the attributes of the subsequent data transaction in the registry) and the No branch of step 201 (see FIG. 1) is taken, with subsequent steps in FIG. 2 performed as described above in the discussion of FIG. 2.

Load-Filter-Enable

FIG. 4 is a flowchart of a load-filter-enable process included in the process of FIG. 2, in accordance with embodiments of the present invention. The process of FIG. 4 starts at step 400, which follows the Yes branch of step 208 (see FIG. 2). In step 402, based on persisted knowledge 110 (see FIG. 1) including a previous data profile that matches the data profile determined in step 202 (see FIG. 2), operational data rationalization system 104 (see FIG. 1) determines that persisted knowledge 110 (see FIG. 1) indicates a result of a previous inference performed for the previous dataset, where the result includes a data size correction and/or data shape correction that was applied to the previous dataset utilized by a previous data transaction of the enterprise.

In step 404, operational data rationalization system 104 (see FIG. 1) determines filtering rules for correcting the dataset based on the data size and/or data shape corrections.

In step 406, operational data rationalization system 104 (see FIG. 1) updates configurations in persisted knowledge 110 (see FIG. 1) for the current data transaction with the data size and/or data shape corrections determined in step 402 and the filtering rules determined in step 404.

In step 408, based on the configurations in persisted knowledge 110 (see FIG. 1) updated in step 406, operational data rationalization system 104 (see FIG. 1) modifies one or more actual queries and/or one or more data collection scenarios of the current data transaction. The process of FIG. 4 ends at step 410.

Load-Enable

FIG. 5 is a flowchart of a load-enable process included in the process of FIG. 2, in accordance with embodiments of the present invention. The process of FIG. 5 starts at step 500, which follows the No branch of step 208 (see FIG. 2). In step 502, based on persisted knowledge 110 (see FIG. 1) including a previous data profile that matches the data profile determined in step 202 (see FIG. 2), operational data rationalization system 104 (see FIG. 1) determines that persisted knowledge 110 (see FIG. 1) indicates that a data size correction and/or data shape correction was not applied to the previous dataset utilized by a previous data transaction of the enterprise.

In step 504, operational data rationalization system 104 (see FIG. 1) updates configurations in persisted knowledge 110 (see FIG. 1) to indicate that data size and/or data shape corrections are not applied to the current data transaction.

In step 506, based on the configurations in persisted knowledge 110 (see FIG. 1) updated in step 504, operational data rationalization system 104 (see FIG. 1) modifies one or more actual queries and/or one or more data collection scenarios of the current data transaction. The process of FIG. 5 ends at step 508.

FIG. 7 depicts an example of rationalization of operational data using the process of FIG. 2, in accordance with embodiments of the present invention. It should be noted that the rationalization of operational data in FIG. 7 is merely an example, which does not express the full scope of embodiments presented herein. Although FIG. 7 utilizes customer sentiment data 702, embodiments of the present invention process various other kinds of data in operational situations between two or more transacting applications or components. The steps 704, 706, 708 and 710 in FIG. 7 are included in a process provided by a known customer sentiment data management system. In step 704, the customer sentiment data remains static in the known system (i.e., the customer sentiment data is not rationalized by embodiments of the present invention and is not updated to reflect a dynamically changing business situation). In step 706, based on the static customer sentiment data, the known system determines a promotional deal for the entire customer base of an enterprise. In step 708, the known system determines that the promotional deal is not accepted by a sufficient number of customers (i.e., a number of customers exceeding a threshold number). In step 710, the process provided by the known system ends.

The steps 712, 714, 716 and 718 in FIG. 7 are included in a process provided by one or more embodiments of the present invention. In step 712, operational data rationalization system 104 (see FIG. 1) rationalizes customer sentiment data 702. In step 714, based on the rationalized customer sentiment data, operational data rationalization system 104 (see FIG. 1) determines a promotional deal for the entire customer base of the enterprise. In step 716, operational data rationalization system 104 (see FIG. 1) determines that the promotional deal is accepted by a sufficient number of customers because the promotional deal was generated based on the rationalized customer sentiment data. In step 718, the process provided by operational data rationalization system 104 (see FIG. 1) ends.

In one embodiment, program code (not shown) for augmentation gateway 106 (see FIG. 1) is included in memory 804 or computer data storage unit 812.

Memory 804 includes a known computer readable storage medium, which is described below. In one embodiment, cache memory elements of memory 804 provide temporary storage of at least some program code (e.g., program code 814) in order to reduce the number of times code must be retrieved from bulk storage while instructions of the program code are carried out. Moreover, similar to CPU 802, memory 804 may reside at a single physical location, including one or more types of data storage, or be distributed across a plurality of physical systems in various forms. Further, memory 804 can include data distributed across, for example, a local area network (LAN) or a wide area network (WAN).

I/O interface 806 includes any system for exchanging information to or from an external source. I/O devices 810 include any known type of external device, including a display device, keyboard, etc. Bus 808 provides a communication link between each of the components in computer 102, and may include any type of transmission link, including electrical, optical, wireless, etc.

I/O interface 806 also allows computer 102 to store information (e.g., data or program instructions such as program code 814) on and retrieve the information from computer data storage unit 812 or another computer data storage unit (not shown). Computer data storage unit 812 includes a known computer-readable storage medium, which is described below. In one embodiment, computer data storage unit 812 is a non-volatile data storage device, such as a magnetic disk drive (i.e., hard disk drive) or an optical disc drive (e.g., a CD-ROM drive which receives a CD-ROM disk).

Memory 804 and/or storage unit 812 may store computer program code 814 that includes instructions that are carried out by CPU 802 via memory 804 to rationalize operational data. Although FIG. 8 depicts memory 804 as including program code 814, the present invention contemplates embodiments in which memory 804 does not include all of code 814 simultaneously, but instead at one time includes only a portion of code 814.

Further, memory 804 includes an operating system (not shown) and may include other systems not shown in FIG. 8.

Storage unit 812 and/or one or more other computer data storage units (not shown) that are coupled to computer 102 may include persisted knowledge 110, initial transacted dataset 112, and/or final transactional dataset 124 (see FIG. 1). In one embodiment, storage unit 812 is data repository 108 (see FIG. 1).

As will be appreciated by one skilled in the art, in a first embodiment, the present invention may be a system; in a second embodiment, the present invention may be a method; and in a third embodiment, the present invention may be a computer program product.

Any of the components of an embodiment of the present invention can be deployed, managed, serviced, etc. by a service provider that offers to deploy or integrate computing infrastructure with respect to rationalizing operational data. Thus, an embodiment of the present invention discloses a process for supporting computer infrastructure, where the process includes providing at least one support service for at least one of integrating, hosting, maintaining and deploying computer-readable code (e.g., program code 814) in a computer system (e.g., computer 102) including one or more processors (e.g., CPU 802), wherein the processor(s) carry out instructions contained in the code causing the computer system to rationalize operational data. Another embodiment discloses a process for supporting computer infrastructure, where the process includes integrating computer-readable program code into a computer system including a processor. The step of integrating includes storing the program code in a computer-readable storage device of the computer system through use of the processor. The program code, upon being executed by the processor, implements a method of rationalizing operational data.

While it is understood that program code 814 for rationalizing operational data may be deployed by manually loading directly in client, server and proxy computers (not shown) via loading a computer-readable storage medium (e.g., computer data storage unit 812), program code 814 may also be automatically or semi-automatically deployed into computer 102 by sending program code 814 to a central server or a group of central servers. Program code 814 is then downloaded into client computers (e.g., computer 102) that will execute program code 814. Alternatively, program code 814 is sent directly to the client computer via e-mail. Program code 814 is then either detached to a directory on the client computer or loaded into a directory on the client computer by a button on the e-mail that executes a program that detaches program code 814 into a directory. Another alternative is to send program code 814 directly to a directory on the client computer hard drive. In a case in which there are proxy servers, the process selects the proxy server code, determines on which computers to place the proxy servers' code, transmits the proxy server code, and then installs the proxy server code on the proxy computer. Program code 814 is transmitted to the proxy server and then it is stored on the proxy server.

Another embodiment of the invention provides a method that performs the process steps on a subscription, advertising and/or fee basis. That is, a service provider, such as a Solution Integrator, can offer to create, maintain, support, etc. a process of rationalizing operational data. In this case, the service provider can create, maintain, support, etc. a computer infrastructure that performs the process steps for one or more customers. In return, the service provider can receive payment from the customer(s) under a subscription and/or fee agreement, and/or the service provider can receive payment from the sale of advertising content to one or more third parties.

The network may comprise copper transmission cables, optical transmission fibers, wireless transmission, routers, firewalls, switches, gateway computers and/or edge servers. A network adapter card (not shown) or network interface (not shown) in each computing/processing device receives computer readable program instructions from the network and forwards the computer readable program instructions for storage in a computer readable storage medium within the respective computing/processing device.
